Abstract
Two-sublattice molecular field theory (MFT) is employed to describe th e temperature dependence of magnetization for (GdxY1-x)(3)Co11B4 compo unds. Three molecular field coefficients, n(RCo), n(CoCo), n(RR) have been calculated by a numerical fitting process. MFT with a single coef ficient provides quite a reasonable description for Y3Co11B4. For X > 0, we find that n(CoCo) is the largest coefficient, implying that the magnetic interactions are dominated by exchange between cobalt 3d elec trons. (C) 1998 Elsevier Science B.V.
